Description

A kind of modular combination floor and construction method
Technical field
The present invention relates to architectural engineering technology, the modular combination floor and construction party of specifically a kind of building construction Method.
Background technology
Prefabricated concrete structure refers to the knot formed using the precast concrete component and fitting of plant produced in assemble in site Structure, have installation rate it is fast, to job site pollution less, construction quality be readily obtained the advantages such as guarantee, have in China extensive Application prospect.Floor is a part for prefabricated component and fitting in prefabricated concrete structure, and its way includes prefabricated(Prestressing force) Concrete slab, reinforced concrete laminated floor slab etc..But this two kinds of ways are defective:The former is whole by assembled floor Body is poor, and is only capable of unidirectional power transmission;And the latter's standardization level is not high, and there are a large amount of wet trades in scene.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of modular combination floor and construction method, this combination building Plate is spliced by the blocking criteria plate of prefabrication, good integrity, it is possible to achieve two-way power transmission.
The present invention provides a kind of modular combination floor, it is characterised in that:The overall on-gauge plate by rectangular module of floor Continuously it is spliced in same plane, the length of side of on-gauge plate is 0.3 ~ 2.4m;
The on-gauge plate lower floor is steel frame, and the top surface of steel frame is equipped with concrete layer, and the lateral edge of concrete layer is relative The side of steel frame inside contracts 25 ~ 150mm;
The steel frame is that four sides channel-section steel surrounds hollow entirety, and the web of channel-section steel is vertical with concrete layer, and notch is inside, channel-section steel The wing plate of top surface is fixedly connected with concrete layer;
Abreast be embedded with bar-mat reinforcement with concrete layer in concrete layer, bar-mat reinforcement stretch out the side 50 of concrete layer ~ 250mm。
Preferably, the lateral location of concrete layer is stretched out in bar-mat reinforcement, concrete layer is provided with multiple 40 ~ 125mm that concave Link slot.
Preferably, the peg being fixedly connected with steel frame is provided with the range of concrete layer covering.
The web of channel-section steel is provided with bolt hole, and installation or modularization mark are connected with building girder or post from side for floor entirety Splicing between quasi- plate.
Wing plate in channel-section steel bottom surface is provided with bolt hole, and installation is connected from bottom surface with building girder or post for floor entirety.
A kind of above-mentioned modular combination floor construction method, it is characterised in that:Order is carried out as steps described below:
The first step, in the prefabricated on-gauge plate of factory's batch;
Second step, transport on-gauge plate are to job site, ground or in the air according to the design shape and size of floor at the construction field (site) Overall floor is spliced into, in splicing:
First by adjacent on-gauge plate horizontal alignment, after the web alignment of steel frame, the adjacent abdomen with connecting bolt through alignment The bolt hole of plate and fastening, the bar-mat reinforcement of adjacent position is secondly tightened into connection, form floor semi-finished product;
3rd step, floor semi-finished product are lifted into design floor location, are fixedly connected from side or bottom surface with building girder or post, so The fill concrete slurry in the groove of slab surfaces afterwards, and, maintenance and solidification by stipulated time concordant with concrete layer.
When floor is connected from side with building girder or post, first, from the steel frame web of edge on-gauge plate to connecting building Beam or post side are fastened with screw or bolt, then recessed with connecting building beam or post on the outside of the concrete layer of edge on-gauge plate Fill concrete slurry in groove, and floating, it is curing by the stipulated time.
When floor is connected from bottom surface with building girder or post, first, connecting building beam or post steel in contact on-gauge plate bottom Locations of structures, lateral connecting building beam or post are fastened with screw or bolt out of steel frame bottom flap, then in edge standard It is and floating with fill concrete slurry in the groove of wall on the outside of the concrete layer of plate, it is curing by the stipulated time.
For the floor semi-finished product when installation on ground forms, the floor semi-finished product are the overall floor that the position need to install A part, after floor semi-finished product are connected from side or bottom surface with connecting building beam or post, new in vacant locations extension splicing On-gauge plate, alignd side by side from side by new on-gauge plate steel frame with the on-gauge plate steel frame of floor semi-finished product, with bolt connection Fastening, connects on-gauge plate the building connecting building beam or post steel construction that are overlapped to floor one by one, and with connecting building beam or post spiral shell Tether and connect, finally the fill concrete slurry and floating in the groove that top surface occurs, it is curing by the stipulated time.
In the first step, it is in the process of the prefabricated on-gauge plate of factory's batch:Steel frame prefabricated first, then in the mixed of steel frame Peg is welded and fixed in solidifying soil layer coverage, the template of correspondingly-shaped is installed afterwards, pours into a mould concrete, it is pre- in concrete layer Bury the bar-mat reinforcement in direction in length and breadth;Etc. to be solidified.
The prefabricated and live bolt of batch production that the present invention realizes floor quickly splices, and floor is realized that standardization is prefabricated, Modular structure is hardly limited by live true form size, can live Fast Installation as the case may be.
The composite floor of the present invention is by side(Square)The blocking criteria prefabricated board of shape is spliced.On-gauge plate lower floor is steel framework Frame, the top surface of steel frame are equipped with concrete layer, connected between concrete layer and steel frame by shearing-resistant member, each steel frame It is connected by screw bolts between corner, the preset slot between every piece of on-gauge plate pours reality using coagulation soil scene.
The present invention realizes the laying of blocking criteria plate for the floor of Different Plane size, and scene is completed assembly, had Standardization level height, floor good integrity, high capacity and two-way power transmission, situ wet operation is few, installs the advantages that quick, application Have good prospects.
